Check Digit Verification of cas no

The CAS Registry Mumber 113366-80-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,3,6 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 113366-80:
(8*1)+(7*1)+(6*3)+(5*3)+(4*6)+(3*6)+(2*8)+(1*0)=106
106 % 10 = 6
So 113366-80-6 is a valid CAS Registry Number.

Synthesis and molecular structure of new phosphorous-crown compounds containing the thiophosphoryl group

Declercq, Jean-Paul,Delangle, Pascale,Dutasta, Jean-Pierre,Van Oostenryck, Luc,Simon, Pascal,Tinant, Bernard

, p. 2471 - 2478 (2007/10/03)

The synthesis and characterization of four phosphorus macrocycles (1-4) are reported. The X-ray crystal structures of compounds 1-4 and solvate 1-H2O show the molecules in asymmetric conformations with at least one methyl group of the phenoxy substituants oriented toward the centre of the macrocyclic cavity. Variable-temperature 1H NMR experiments show that in solution the molecules exist mainly as rapidly interconverting conformers. In the 18-membered ring 1, the dynamic process results in the enantiomerization of asymmetric conformers with a barrier of 8 kcal mol-1.? The 21-membered ring 3 is more flexible and exists in several conformations.
